. which said turret is mounted; impression de-v vice carriers, severally mounted on said independently rotatable shafts, respectively; and -a spiral gear wheel mounted on and ro- 4o tating'with saidturret. v

` The other elements herein shown and described may, ina general way, be said to include a reservoir forl ink;- mechanism for e'qualizin' Athe distribution of said ink upon the-perip eries of rollers, p riorly Ato the ap- 'plicatio'n thereof to `the 'impression devices, fand'inechanism for effecting such ap lieation fof-'the `properly distributed lnk for W ch see,

nordert'o identify elements shown in 'application; vreced'en't hereto and hereinbefore referre to, distinctively from-'elements l, more 4immediately connected with this -application, small, or so-calle'd` "lower- 'case.l

Figs. 41 to 46, inclusive, are, sev-` ferly adapted totlie uses for which'tleiy are 'letters will be -usedsolely as reference marks lfor the former onl -The'referen'ce marks viisedhereilnare,v re atively, alike throughout this specification. The 'turret t, may be rotated :by any suit- 7o able means. (Not .'sh'own.) The independently rotatable shafts s, may be selectively and variably rotated', and also reciprocated axially, by means of the lrotation of the turret t, combined with the operations of mechan- 75 .isms lfully described in the before-mentioned v application the operations of said mechanismbeing selectively' originated by manipulations o keysl c. "'Also, by the rotations of ,l the turret t, when combined with a down-fo Ward reciprocation of a shaft s', two other sep arate and distinct results may be obtained;

and "hereinbefore mentioned.

' Yet another:'"kinetic connection is -madef with the turrett; namely, by means cfa spiral gear lwheel w, which meshes 'with a spiral pinion p, mounted on and rotating a wo'v shaft 2,- on which 'isalso mounted a'second spirall gear wheel, which meshes with a spiral gear Wheel 1,journal'ed, by a hub thereon, in

.the framework F, of the machine'. The wheel 4 hasa'socket 4 ,formed axiallythereof; and xo 5 is therebyV adapted to receive, and to enga e for rotation,,a flattened end 5,' of a spinde or shaft`5; the end 5. being retained in said socket 4', by a vspring .5 On the shaft 5, is

mounted a gear Wheel 6, rotatingtherewith no and meshing with-a gear wheel 7., mounted on and rotating with a shaft 8, which is journaled vin a 'bracket B, and is laterally mov# V.ableat itsupperportiom where it carries an ink-distributing roller 9, lwhich 4peri'r'iherally 115 contacts with an'inkcon-veying roller 10,*a`nd with an"inkapplyin g, or inking rollerwli; the latter'being mounted on the.up'r'erend of as'haft 12. 4Contact 'of the peripheries of ythe inking-rollerll', ink-distributinguoller 9', i zo l and ink-'conveying roller 10, -m-a .lee `maintained byim'eansof pressure-rol ers, 13, 13,

may, for convenience sake, be mounted in an appurtenance "195", and by .reason of such mounting 'may be readily removed from the .inachine; -either l engagement or disengagementoffthe drive-shaft 5, "thereof, with a driving member, such. as-4, Vbeing readily effected by means of the shaft end 5 'and the 'socket 4.

A type, orinpression-'devioe d, being'inlced as aforesaid ,if it be intended toprint color therewith, or'otherwiseleft uninked, may be impressed on, agains'tior into theimpre'ssiom may be urged `toward .the impression" devices d, andagainstj a stop 23, by' a spring 24,' which'is mounted. on a screw :stud 25,. which also. passes through' an' adjustable tubular thumbs'cr'ew 26.,.andri's tapped into the platen' 20.' The thumbscrew 2 6., is peripherally l grooved nearits-inner end, and, at that'part, may-be located between', fizgcedcurved jaws apart from the resilience-thereof.

which may be integral with the platen 20.

The screw-threaded body of the thumbscrew 26, may engage Withga female screw thread formed in a clamp-nut 2 1" which may be integral with the platen guide-member 21, and' be furnished with a clamping screw 22, mounted in the usual manner, to clamp the nut 'on' the thumbscrew 26, and thus prevent the latter from rotating. 'A pair of adinstable jam-nuts 27, 27, may be mounted near the'outward' end of the screw 25', and serve to regulate the tension of the 'spring 24, Whichabuts against one of ,them and also againstthe outward end of the thumbscrew 26. `rThe impact-receiving face of the platen 20 may normally lie on, yor approximately near, the plane 'of the rear surface vof the iinpress'iorrreceptive material. i

By the operation of the mechanisinthus described, a resiliently-operative surface is presented to receive the impact when an im` pression is being made the amount of resili-4 ence of such operation may be regulated' at will 5 and a separate adjustability is avail- 'i able for regulating the force of the impact As the guide-rail 23, as shown, moves with the carriage 100, transversely yof .the niachine; and as it is necessary that the platen 20, should 'be retained in a fixed position relative to said transverse motion, in order `to properly receive. the' impact of the impression-devices, means for. effecting such. retention, maybe provided as follows; (see, more.

particularly, Figs. 1, 12 and 13.) A-link 30 platen'guide-member 21 and at the' other Ven'd thereof, to -a curved bracket 33, which vmay be ,located at one side of the machine.

The bracket 33,-may be pivotedto the frame F, Aandthe curve 33', thereof, 'may be of such Hage-,160, to be movedto'its extreme posi- --tion nearest. to the bracket 33, without conf tacting the latter Referring now to Fig. 138, i-t vwillsbeseen that the pivot 'of the curved 'bracket 33, may in forni, be a bush 34, furnished with al' iange '34 and secured,

.by a binding-screw 35, passing therethrough,

tothe bed Ff ofgthe machine.v The flange tata'bl'e position between said flange 3:4 and thesurface of thebed F.. -In thelatter may IOO -may be hinged at one en'dthereof to the-' -for'rnjand dimensions as to permit the carl 734', serves to retain the bracket 33, in a rol be'form'ed a conical recess-36,'in which a conlical 'detent 37,- returnablyoperative by a spring 38,- rnay. be engaged. The conical de- -tent 37, isforrned on an end of a cylindrical body 37, which' Vhas astenn-portion. 37,

around which the returnin -spring 38 may be.. i

Wound. The detent an .spring .may be .mounted in acounter-boredV cylindrical ecess in the ,foot 33, of the curved bracket 3 3 thelspring 38, abutting, at'onefend, against v.

the; shoulder- 39', in said recess, and, at the other, end, against a sliould'erfon the'iletentbody 37'. Engagement of the conical detent 37, in the recess 36, may serve to retain the curved bracket in position to admit necessary, in which event the conical detentV within the curve 33', a part of the carriage 100, when the latter is at its prime, or linebeginning position. At other ti-mes, the curved bracket 33, may be turned aside, if

37, will recede from the recess 36, and rest upon the surface of the bed F'. hereinafter set forth, the hinges 31, 32, connecting the link 30, tothe platen 20, and to .the bracket 33, res ectively, are preferably formed as universa joints g (see, more particularly, Figs. 1 and 12 ,and Figs. 13-'to 17, inclusive g) thus allowing to 'the'carriage 100, with the .platen guide-member 21, a rocking movement longitudinally of the machine.

Feeding movementsl of the impression-receptive .material are provided for, in two directions, by this invention andin the form sh-own herein as one illustration of the-latter,

one of said movements is designed to engageably introduce the impression-rece tive material into the machine and to feed 1t longitudinally thereof; or s o as to provide for successive lines of impressions which may be `made transversely thereof,l and comprises a roller feed, with suitable operative mechanism. The piyoted links 29, with the guiderail 28, rigizll'y.` secured to each of them, form an oscillatable frame; (see, more particularly, Figs. 3 and 32.) Each link 29, has a projection or shoulder 29",v formed transversely thereof, which serves to contactwith a suitably-formed surface on the frame F thus limitin thie oscillatory motion of the links 29, an of members mounted thereon.

, A feed roll shaft 41, is journaled inthe links 29, at the 'free ends of '.thfe latter, and on the shaft 41, is rotatably mounted a feed-roll' 40, which may be providedwith a knurled collar 40', by which it may be manipulatively'rotated.- (See now, Figs. 1, 8, 8, 11, 12, -19 and 20.) To, and concentric with the feedroll 40, is secured a' feed-wheel 42; which is provided with ratchet'teeth, and ma be operated in intermittent partial rotations, by

means of a vpawl 43, which isv provided withv an arm 43', integral therewith, and is oscillatably mounted on a pivot 44', fixed on a i .lever 44, which,'by its oscillations, serves to actuate the line-feed mechanism now being described. To the lever 44, is pivotally connected a link 45, which is also connected to a slotted lever 47," by. means of a pivot 46,

which, may be adjustable in the slo t,47",.in

.the let '47. The pivot 46, may be fur-- nished with a .knurled binding nut 46', b which it may be xed in position when a justed. -The lever 47, is oscillatably mount- .j ed on a pivot 47. B adjusting the pivot 46, and by meansv o Hthe mechanism described, the intermittent artial rotations of the feed-Wheel 42, anda so ofthe feed-roll- For reasons 40, to which it is secured, may be proportionately regulated. The pa'wl 43 may beV retained in engagement with the teeth of the feed-wheel 42, by means of an angular lateral projection 43", on one side of the former, which projection by means of a spring 43' mounted on the pawl-pivot 44', is ur ed into an angular recess 44", inthe side of t e lever 44, in order to eHect ay resilient coactive en'- gagement'of the latter with` the feed-wheel 42, by ,meansof the pawl 43. A second angular recess may be formed in the lever 44, as at 44', into which the-projection 4 3", may. be urged by the spring 43"', in orderlto prevent the'pawlv43, from en aging with the .teethof the feed-wheel 42 t e pawl-arm 43',

serving asa manipulative means for effecting the engaglng and disengaging operations described. A check-wheelA 48, secured to, and mounted concentrically with the feed-wheel 42, may be provided with angular teeth,

which,being enga ed by a s ring-detent 49,

which is fixed to t e frame may serve to prevent accidental rotative movement of the feed-roll 40, in either direction and to prevent a reverse movement thereof such as .100. An arm 53, is also fixed .on the-pivot 52, in such a position, that when the carriage Ico 100, is moved from left to right,' an'd ap'-,

proaches the limit of its movement, the arm 53 is intercepted by a stop 54, which is fixed to the b ed F', of the machine, and causesthe miter-wheel segment 51, and, by means arm 53, to, partially rotate the pivot 52,v and thereof, the miller-wheel se meant 50, on the pivot 47',`thus causing the ever 47, to oscillate and to operate the line-spacing mechanism. A returning-spring 5 5, of which one end Iis fixed, by a stud 55'-, to the carriage 100, the other end vbein attached by a stud 55" to the load arm of t e Alever 47,. serves to return the line-spacing mechanism to its zero, or non-operative position, and to maintain the arm 53, in position to contact'with the stop 54. By moving forwardly the pawlarm 43', theA p'awl 43, becomes disengaged from the teeth of the feed-wheel 42, and the feed-.roll 40, may be rotated, Iin either direction, by means of the knurled collar 40'. By

moving 'backwardly the pawl-arm 43 the pawl 43, is positioned to engage the teeth of the feed-wheel 42.

In order to render the tionallyoperative, pressure rolls 56, may be provided, designed to hold the impressiom' receptive material against the periphery of lfeed-roll 40', funcl sesgos .the leed-roll 40. .The rolls56, may-begin number, as many as' maybe required; but as' shown, herein, they comprise two shortlrolls.

. -The 'peripheries thereof,I and 'of the feed rolll 5 4Q, or lof some of. them, maybe'composed of rubber orl some other elastic substance',` in

orderto insure. a feeding action thereof,-

.- The pressure-rolls 56 V(see," vv more 'partiell'v l larly, Figs. 14 to 17, inclusi-va) are severally.

By again referring to my prior application,

hereinbefore referred to, it will be seen that a shaft s, may be depressed in the turret t, and the latter'may then be rotated, without necessarily functionallyoperating an impression device. Therefore, should it be desired to so operate the letter-spacing mechanism as'to leave blank spaces on-the impressionreceptive material, as, for instance, between words, the desired object maybe attainedl by the o 'eration of certain keyselc' in the key-boar l7c, shown in Fig. 2; bywhichsaid operation; thenecessary spacing result may' '..position of the-machine asshown in the .l of a' complementary angle-face 70', of the j frame F, and secured to the latter by a bindy ing-'screw 71";.'said angular memberT-l, by

Referringfnow, more particularly, to Figs. 23 to. 28,`v inclusive, it will lbe seen that, in order to insure an absolutely positivelimitation of movement'ofthe carriage 100, inthe direction involvingl letter-spacing, and to prevent the momentum ofa moving parts from causing a continuance -of their movement bey'onda normal point, the star-wheel arms 63', consecutively 'engage an angular detent 7 2, which is pivoted at 72b, to the bedis, practically in an approximately vertical position when at zero, and the other arm 72", contacts with an adjusting screw 72"',

which may be tapped into the bed F', and' serves to yregulateI the amount of movement 'plate F'. One arm 72', of said detent .72,`

toward' which it is returnably urged by a spring 72a, Fig. 23. The rotatory motion of. the star-wheel 63 is right-handed, or as from North to East. e rection, the arms`63' contact with abackstop 7-3, which is pivoted at 74', to abracket 74, .which is secured tothe bed F'. .The back-stop .73, isof such form that it may lie partlyin an'd partly. out of thev path of the 'arms 63', being 'returnably held in such position by a spring 74"'. A toe 73' 'on the back stop 73, engageable with a cross-pin 74", in the bracket 74, limits the movement, in one direction, of the back-stop 73, to a .position in which the free end of the latter may contact in turn, with one side of each seweral arm'63', of the star wheel. When .the star-wheel 63, is partially rotated, an arm 63' frictionally engages the upper surface Iof the 'back-stop 73, and depresses the latter below the path of the former; but

`when the arm 63', passes the back-stop 7 3,

ln my present invention, means are provided, (see again, more particularly, Figs. 9 and 10, and 30 to 35, inclusive) for both automatically and manipulatively engaging and disengaging the letter-spacing mechanism of the carriage, and also, as before alluded to, (see Figs. 4, 11 and 18,) of'automatically effecting a return of the carriage 100,4 to a prime, or line-beginning position, when said letter-spacing mechanism has I In the form shown herein as an illustration thereof, a

cylindrical stud 75, having a head 75', and

va threaded portion 75", is screwed into a lug on the frame F above which the stud' 75 projects, and against the lower portion of which the head 75' contacts. A sleeve 76, rotatably'mounted on the stud 75, may, in general terms, be described as a cylindrical body having a flange 76' thereon, and a shoulder 76", formed by a reduction in din ameter of a portion of said body.l A disk 77, is rotatably mounted on the sleeve 76, and is counter-bored to t over the flange 76', A. coiled' spring 76, may have the inner end thereof attached to the sleeve 76, by a pin 78', and the other end thereof attached to a Worm Wheel 79, by a pin 77. 1l-testing on 'the shoulder 7 6",

is the Worm-pheel 79; rotated by a Worm threaded member'SO, Which is rotatably mounted iny the machine frame F, and is furnished with a knurled head 80'. To the disk 77, is attached an end of a flexible-member, such, for instance, as a tape 81, which may be coiled upon the peri' hery of said disk 77 and may be attached), at its nother end, to the pendent-member 101, of the carriage 100, as hereinbefore stated. Requisite tension of the tape 81, may be maintained by adjusting that of the spring 78,

by rotating, by means ofthe knurled head 80', the vWorm-threaded member 80; which, m turn would rotate lthe Worm-Wheel 79, and the sleeve 7 6, to whichthe innerend of the coiled spring -78 is attached by means of the' sioned, tends to rotate the pin 78'. The spring 78, being properly tenisk 77, which, in rotating Will Wind upon its periphery, the tape 81, Which is attached to the pendentmember 101, ofthe carriage 100, and will thus continuously urge the latter toward its.

prime, or line-beginning position, namely at the extreme limit of its movement at the right of the machine, the latter being considered in its normal position relative to a personal operator; in which position the machine will be assumed to rest, relative to the directional terms herein used.

In Fig. 4 a compound or tandem tension" spring is show-n for applying tension to the drum 77. In this instance the spring 78 is fast to the sleeve 76 and engages a pin 79' carried by the member 79, and the spring 78" is fast to the sleeve 76 and also engages a pin 77 carried bythe drum 77. By this means both of the springs will act in harmony and y space is economized in this structure.

The several means for effecting the engagement of the line-spacing mechanism, and for disengaging the same, both of which operations 'may be performed either automatically.' or manipulatively; and means for retaining said mechanism in engagement, may be described as follows On the pendent member 101, (see now, more particularly, Figs.4 9, 10, broken lines in 11, and .30 to 3,7, inc usive,) of the carriage 100, and lying longitudinally thereof, is a locking-member '82, Which may consist of a rib 82', integral with the carriage; and of two guide-blocks 84 and 85. The locking-rib 82', may be either rectangular in cross-section as shown, or of any suitable form adapting it to eHect a transverse locking engagement of either of its sides with a suitable contactingI member; such, for instance, as is shown herein as a spring-returned reciprocatable guidepin 83, (more particularly shown in Figs. 2a and 21),) mounted in the frame F.

The guide-pin 83, may be formed as a cylindrical member, having a contact projection 83', bod 83", and a stem 83"'; and may be mounte partly in a counter-bored. recess 91 formed in the frame F, andpartly in a court ter-bored recess 92', which is formed in a c vliiidriforin member 92, and contains a helical spring 93, which surroundsv the guide-pin stem 83"', and impinges'a` vainsi the shoulder of the guide-pin 83, an also against the shoulder formed in the recess 92', .in the member v92. The latter is l partly screu` threaded externally, and screws-into a-female thread in the recess 91. The contact-projection 83', from the guide-pin 83, may preferabl be rhomboidal in cross-section, and the en thereofmay .be slightly rounded longi;A

'tugj/nally of the rhomboid, and angular trans# versely thereof; such 1 conformation being adapted to properly con tact with the severa -coacting parts of the locking-mcniber 82.
